Make the transition visible and accountable.
Organize source, destination and data scope into a migration project. Track work and exceptions to support cutover planning and validation.
Assess mail, calendars and contacts separately.
Mail connections can use IMAP, Google Workspace or Microsoft 365 depending on the environment. Calendars use CalDAV, Google Calendar or Microsoft Graph; contacts use CardDAV, Google Contacts or Microsoft Graph. Validate endpoints and permissions separately for each workload.
Pilot before scheduling the move.
Confirm connections and access, then test folder or collection mapping with representative accounts. Use the results to plan batches, user communications and acceptable cutover windows.
Track progress and handle exceptions.
Review migration progress and status. Mail work provides folder-level information to help investigate skipped or failed items; calendars and contacts track progress by collection. Completion status still needs to be checked against agreed validation criteria.
Conditions and limitations
APIs, permissions, service limits and data formats affect results. Check message size limits, special events and field mapping during the pilot. Unchanged transfer of all data in every environment is not guaranteed; scope follows assessment and validation.
Prepare for a demonstration
Bring your source and destination systems, estimated account count, data types and preferred cutover timing. We can discuss suitable connections and validation methods. No passwords are needed for an initial conversation.
Frequently asked questions
Can mail, calendars and contacts be assessed together?
Yes, but each workload has different connections, permissions and formats. Validate source and destination support separately; a successful mail test does not validate every workload.
What should happen before migration?
Confirm data scope and account mappings, pilot representative accounts, then plan batches, user communications and cutover timing around the results.
What should we check after a job finishes?
Validate data and exceptions against the agreed scope. Check folder, calendar or contact collection mappings before handover.
